Emily Blunt Turned Down AI for Crucial Scene in 'Disclosure Day,' Creating Sounds Herself Instead

Emily Blunt has shed light on her decision to sidestep artificial intelligence while working on her forthcoming Steven Spielberg film Disclosure Day, discussing the creative process behind one of the movie's most demanding sequences.

The 43-year-old actress, known for her role in The Devil Wears Prada, recently sat down on Hot Ones to discuss a particularly intricate scene that posed unique challenges during production. The sequence called for her character to produce vocalizations in an otherworldly language, and while AI-generated audio presented an available option, Blunt was hesitant to pursue that path.

"It's a four-minute oner that we shot that leads up to that moment where she's gradually sort of disintegrating," Blunt explained. "There's various ways you could do it. You could go the AI route, which I'm a bit terrified of. I thought I could make some really strange sounds."

Instead of delegating the work to technology, the actress opted to generate the sounds herself. She came to set prepared to experiment with a variety of vocal techniques and unconventional noises. "I said maybe I could come in and we'll just do a range of weird sounds. And it's what we did," she revealed. "I did sort of the clicking sounds, I did sort of humming sounds, consonant sounds, breathing strange sounds."

The production's sound design team then took those raw vocal recordings and crafted them into the final audio effect featured in the film. Using specialized microphone placement and advanced audio processing techniques, the sound department built the various elements Blunt had created into what she called the completed "weird sound" heard in the scene.

Her approach reflects broader industry discussions about AI's expanding role in filmmaking and whether automation should supplant traditionally human-driven creative contributions.

Disclosure Day arrives in theaters June 12, 2026.
